Cole Palmer was hugely influential as Chelsea saw off Newcastle in the Premier League at Stamford Bridge.
Palmer struck in the 57th minute, taking a touch to get the ball out of his feet before drilling hard and low past goalkeeper Martin Dubravka.
The Blues had gone ahead early after Sven Botman's poor clearance was pounced on by Palmer, his shot being cleverly steered into the bottom corner by Nicolas Jackson for his second goal in as many league games.
Aleksander Isak's powerful effort from the edge of the area just before the break gave Newcastle hope before Palmer restored Chelsea's lead.
